GUN-'MOUNT.

Application file-:1 May as, 1817.

Be it known a citizen the United Sta 1 lltica i in the county of Oneida and state or ev-r Y have invented certain new and useful Improvem nts in Gun-Mounts, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to a gun mount, and I declare the following to be a full, clear, concise, and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The object of the invention is to provide a simple, ei'iicient mount for machine guns, whereby the sa may be carried upon automobiles or ships or other conveyances, in suc-h a manner tl the sighting surface of the same will be held always on a level, so that the guns can aimed accurately not withstanding the rolling or tipping of the conveyance. Furthermore, the mount is adapted to permit the gun to be moved and ield at any desired angle.

The object will be understood by referring to the drawings inwhich:

Figure 1 is perspective view of the gun mount supporting a machine gun;

Fig. 2 is an enlarged detail view of a rod and sleeve mounted. thereon that is employed;

Fig. 3 is a detail view partly in section, showing the manner of connecting the hanger to a yoke that is employed in the construction Fig. 4 is an elevation of the device, showing the lower portions in section;

Fig. 5 is an enlarged detail view of a yoke employed.

Referring more particularly to the drawings, the gun mount embodies a base -1 having an annular elevation 2 over which fits in a loose manner, the rotary disk 3 provided with an annular recess for the purpose. T he disk 3 is held in mounted position by the headed bolt l and nut 5. The under surface of the base -1 is recessed at 6 to give clearance for the head of the bolt 4. Brackets 7? are fixed to the rotary disk 3, which brackets aid to support the standards 9-9 attached to said brackets 7 by bolts 8.

Specification of Letters Patent. Patqgntggfl App 23, 1929,

Serial No. 171,239.

Furthermore, the standards 9 are held in ii? ,d relation to each other by the rods 10 projecting through holes in the standards 9 and the nuts 11 screw mounted to opposite ends of said rods 10. Sleeves 12 are mounted upon the rods 10 and act as spacers between'the standards 9. The upper ends of the standardsl) are arched to provide overhanging portions 13. These overhanging portions 13 have formed therein journals for the reception of the trunnions 15 of the rotary yoke or member 16. The yoke 16 has formed on its opposite ends the bosses 1717 adapted to bind against the contiguous surfaces of the standards 9 when the nuts 18 are tightened, whereby to hold the yoke 16 at any given angle with respect to the standards 9.

The yoke 16 is provided with an annular recess 20 adapted to receive the correspondingly projecting portion 21 of the hanger 22. El raceway for balls 23 is formed within the edges of the annular recess 20 of the yoke 16 and within the projecting portion 21 of the hanger 22, whereby to reduce the friction between said parts, so as to permit the easy turning of the hanger 22 relative to the yoke 16. A headed bolt 25 and nut 26 hold the hanger 22 in assembled position to the yoke 16.

The upper end of the hanger 22 is provided with a recess 27 adapted to receive the correspondingly shaped member 28 formed on any gun, such as 29. The lower end of the hanger 22 is bifurcated at 23 to receive the tongue 24: formed integral with the lower part 80 of the hanger 22. A pivot 31. holds the lower part 30 in suspended position. A weight 32 is attached to the lower end of the part 30 of the hanger 22 and thereby holds said part 30 at a vertical angle, whereby to localize its position. The wei ht 82 will cause the hanger 22 to seek normally a vertical position because of the force of gravity acting thereon.

In operation, the gun 29 is disposed with the member 28 thereof within the recess 27 the hanger 22. As thus mounted, the gun 29 can be swung at any angle in either a vertical or horizontal plane because of the rotary disk 3 that turns in a horizontal plane upon the base 1* and of the rotary yoke 16 that turns in a vertical plane upon the standards 9. Furthermore, the nuts 18 will be tightened sufficiently to'permit a given amount of friction between the bosses 17 and the contiguous surfaces of the standards 9, whereby the gun can be moved and held at the given vertical angle. Moreover, the gun 29 will be held always with its sighting surface on a level plane, no matter, how great may be the tilting of the base l, because of the pivotal connection of? the hanger 22 with the yoke 16, and the pulling downward by the weight 32.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a gun mount, a hanger having a recess for holding a gun, a pivotally mounted weight for holding said hanger in vertical position, a yoke having an annular recess for mounting said hanger, antifriction members disposed in said recess to facilitate the turning of said hanger. standards for pivotally supporting'said yoke, and a revoluble base for supporting said standards.

2. In a gun mount, a hanger having a recess for holding gun, a weight pivotally attached to said hanger, whereby to hold the sighting surface in a level plane, a yoke for permitting the gun to be turned at any given vertical angle, a rotary disk for permitting the gun to be turned at any given horizontal angle, said yoke having bosses and nuts cooperating with said bosses, whereby to hold the yoke at any given angle.

3. In a gun mount, a hanger having a projecting portion, a weight pivotally attached to said hanger, a yoke having an annular recess adapted to receive said projecting portion, antifriction balls disposed in said recess to facilitate the turning of said hanger relative to said yoke, standards for pivotally supporting said yoke, and a revoluble base for supporting said standards.

4. In a gun mount, a hanger having a projecting portion, a weight pivotally attached to said hanger, a yoke having an annular recess adapted to receive said projecting portion, antitriction members disposed in said recess to facilitate the turning of said hanger relative to said oke, standards for pivotally supporting said yoke, a revoluble base'for supporting said, standards, and means for holding said yoke at any angle.

In a gun mount, a pivotally mounted weight for holding the sighting surface of the gun in a level plane, a yoke for permitting the gun to be turned at any given vertical angle, a rotary disk for permitting the gun to be turned at any given horizontal angle, bosses, and nuts cooperating with said bosses, whereby said yoke is held at any given angle.

In testimony whereof I have afiixed my signature.
